Aphrodite Herrington is the only sane one in her unusually large family -- including her parents. The girls, Terpsichore and Athena, are saucy and flirtatious while the boy, Aklepios, runs away from Cambridge and loves to pull pranks. They all converge at a house party meant to celebrate Aphrodite's engagement. The guests include Terpsichore's former beau, Callum McReynolds, who still loves her but is too proud to admit it, and Thomas Warwick, an acknowledged rake who starts to fall in love with Aphrodite just as her fiancé, Frederick, falls for Aphrodite's sister Athena.
When Asklepios shows up masquerading as an Italian count, Aphrodite knows that for once her family beyond her control. Worst of all she finds herself falling in love with Thomas.
They decide to entertain themselves and the guests by putting together a performance of "A Midsummer Night's Dream". And as if written by Shakespeare himself the love affairs begin to unravel.
